[0023] Please refer to Figures 1-5, an embodiment provided by the present utility model: a high-speed grinding and polishing device for copper tubes, including an equipment cabinet 1. A horizontally arranged guide rail 2 is fixedly installed on the upper surface of the equipment cabinet 1. A lead screw 3 is installed inside the guide rail 2 through bearings. One end of the lead screw 3 is fixedly connected to the output shaft of a servo motor 7, and the servo motor 7 is fixedly installed on the outer wall of one side of the guide rail 2. Two symmetrically distributed threaded seats 4 are sleeved on the lead screw 3, and both of the two threaded seats 4 are threadedly connected to the lead screw 3. Fixed rings 5 are fixedly installed on the upper surfaces of the two threaded seats 4, and a grinding outer cylinder 6 is fixedly installed between the two fixed rings 5;

[0024] With this structural design, the servo motor 7 can rotate. When the servo motor 7 rotates, it will drive the lead screw 3 at the top to rotate synchronously through the output shaft. Since there are two threaded seats 4 threadedly connected to the lead screw 3, when the lead screw 3 rotates, the two threaded seats 4 threadedly connected thereto will perform synchronous linear movement along the lead screw 3. In this way, the fixed rings 5 and the grinding outer cylinder 6 at the top are driven to move synchronously through the movement of the threaded seats 4, which is convenient for the movement and sleeving work of the grinding cylinder, improving the use effect;

[0025] Among them, specifically referring to the attached Figure 4 and Figure 5 As shown, a circular grinding sandpaper 8 is fixedly installed on the inner ring of the grinding outer cylinder 6. A polishing inner cylinder 9 is arranged inside the grinding outer cylinder 6. The grinding outer cylinder 6 and the polishing inner cylinder 9 are designed with a concentric structure. A number of strip-shaped grooves 10 are arranged on the outer wall of the polishing inner cylinder 9, and the number of strip-shaped grooves 10 are circumferentially distributed at equal intervals around the center point of the polishing inner cylinder 9. A number of equally spaced polishing scrapers 11 are fixedly installed in each strip-shaped groove 10;

[0026] With this structural design, the grinding sandpaper 8 of the grinding outer cylinder 6 can contact the outer surface of the copper tube after the cylinder is sleeved, and the polishing scrapers 11 on the outer surface of the polishing inner cylinder 9 can contact the inner wall of the copper tube. In this way, the grinding sandpaper 8 can perform high-speed grinding work on the outer wall of the copper tube, making the outer surface of the copper tube more refined, bright, and improving the aesthetics of the outer surface of the copper tube. And through the arranged number of polishing scrapers 11, the burrs on the inner wall of the copper tube can be polished and scraped, effectively completing the scraping and polishing work inside the copper tube, reducing burr residues, and having good structural use characteristics.

[0027] In this embodiment, in order to blow out and clean the debris inside the grinding cylinder, avoid the retention of debris during grinding and polishing in the cylinder body, and improve the cleanliness inside the cylinder body, a rear connecting plate 12 is fixedly installed at the tail ends of the grinding outer cylinder 6 and the grinding inner cylinder 9. A blower 13 is fixedly installed on the outer wall of the rear connecting plate 12 through fixing bolts. Thus, the blower 13 provided can blow out the debris inside the cylinder body, so as to clean the inside of the cylinder body. It has a good self-cleaning use effect, does not require manual cleaning, improves the convenience of the structure in use, and is convenient to use.

[0028] In this embodiment, in order to perform the clamping and rotating work on the end of the copper pipe, a fixed side plate 14 is fixedly installed at one end of the guide rail 2 away from the servo motor 7 and on the upper surface of the equipment cabinet 1. A rotating motor 15 is fixedly installed on the outer wall of one side of the fixed side plate 14 through bolts;

[0029] Furthermore, the output shaft of the rotating motor 15 is fixedly installed with a three-jaw chuck 16. A copper pipe body 17 is clamped inside the three-jaw chuck 16. The three-jaw chuck 16 provided can perform the fixed clamping work on the copper pipe. At the same time, the rotating motor 15 provided can drive the three-jaw chuck 16 and the copper pipe body 17 at the top to rotate synchronously, so as to conveniently complete the comprehensive grinding work on the outer surface of the copper pipe.

[0030] In this embodiment, in order to improve the use effect of the equipment, support legs 18 are fixedly installed on the lower surface of the equipment cabinet 1. A cushion block is provided at the bottom ends of several support legs 18. Among them, a switch door 19 is movably hinged to the front of the equipment cabinet 1 through a hinge. A handle 20 is fixedly installed on the switch door 19.

[0031] Working principle: When it is necessary to grind and polish the copper pipe, the copper pipe adapted to the use of the present utility model can be fixed through the three-jaw chuck 16 (the wall thickness of the adapted copper pipe is a specified size, that is, the outer surface and the inner wall of the copper pipe can just contact the grinding sandpaper 8 and the grinding scraper 11);

[0032] At this time, the rotating motor 15 provided can drive the three-jaw chuck 16 and the copper pipe body 17 to rotate at a high speed through its output shaft;

[0033] When the rotating motor 15 works, the servo motor 7 provided can work synchronously. When the servo motor 7 rotates, it will drive the lead screw 3 at the top to rotate synchronously through the output shaft. Since two threaded seats 4 are threadedly connected to the lead screw 3, when the lead screw 3 rotates, the two threaded seats 4 threadedly connected thereto will linearly move synchronously along the lead screw 3. Thus, the movement of the threaded seats 4 drives the fixed ring 5 and the grinding outer cylinder 6 at the top to move synchronously, so that the grinding outer cylinder 6 can be displaced from the right side to the left side;

[0034] During the leftward movement of the grinding outer cylinder 6 from right to left, the grinding outer cylinder 6 can be sleeved outside the copper tube body 17, that is, the copper tube body 17 is inserted into the gap between the grinding outer cylinder 6 and the grinding inner cylinder 9. At this time, the grinding sandpaper 8 of the grinding outer cylinder 6 can contact the outer surface of the copper tube body 17, and the grinding scraper 11 of the grinding inner cylinder 9 can contact the inner wall of the copper tube body 17;

[0035] Under the high-speed rotation state of the rotating motor 15, the outer wall of the copper tube can be ground at high speed through the grinding sandpaper 8, making the outer surface of the copper tube more refined, bright and improving the aesthetics of the outer surface of the copper tube. And through the arranged several grinding scrapers 11, the burrs on the inner wall of the copper tube can be ground and scraped when the copper tube rotates, effectively completing the scraping and grinding work inside the copper tube, reducing burr residue, and having good structural use characteristics;

[0036] During the process of high-speed rotation and grinding, the blower 13 can be turned on, so that the blower 13 can blow the material in the cylinder, making the debris blown out and improving the internal cleaning effect;

[0037] Among them, in order to increase the grinding coverage area, after the grinding cylinder assembly is sleeved outside the copper tube, the servo motor 7 can rotate intermittently forward and backward, so that the grinding cylinder assembly can move back and forth left and right, thereby effectively improving the contact effect between the grinding scraper 11 and the copper tube and enhancing the deburring effect;

[0038] After the copper tube is ground and processed for the specified time, at this time the servo motor 7 rotates reversely, driving the grinding cylinder assembly to move from left to right to perform a reset process. After the reset, the rotating motor 15 stops working. At this time, the processed copper tube can be taken off through the three-jaw chuck 16, and a new copper tube can be placed to complete the cyclic processing of the processing equipment of the present utility model;

[0039] The high-speed grinding and polishing equipment for copper tubes of the present utility model can be sleeved outside the copper tube by means of sleeving the grinding cylinder assembly, so that the grinding cylinder forms a wrapped state around the copper tube, improving the final wrapped grinding and polishing effect, avoiding dead corners in the grinding area, and improving the use effect. After being sleeved and wrapped, the grinding sandpaper and the grinding scraper of the grinding cylinder assembly can respectively contact the outer and inner walls of the adapted copper tube. In this way, through the high-speed rotation of the copper tube, the synchronous grinding and polishing processing of the outer and inner parts of the copper tube can be completed, and the inner and outer walls of the copper tube can be processed synchronously, improving the grinding and polishing efficiency of the copper tube and having the use characteristics of synchronous internal and external processing;

[0040] Moreover, by using the screw drive structure, the grinding cylinder assembly can be driven to perform linear displacement work left and right. During use, it can perform wrapping-type internal and external grinding work on copper pipes of different lengths, and can be applied to copper pipes of different lengths (the maximum length of copper pipe processing shall not be greater than the length of the grinding cylinder assembly), having good length dimension applicability, improving the overall scope of use, and reducing the use limitations.

[0041] Finally, in the present utility model, a blower is provided. When the grinding cylinder assembly structure is grinding, the blower can blow the grinding debris generated inside, so as to clean the inside of the cylinder body. It has a good self-cleaning effect in use, does not require manual cleaning, improves the convenience of the structure in use, is easy to use, and the overall device has a simple structure, low manufacturing and maintenance costs, and is suitable for popularization and use.

[0042] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
